Service Bus Batch Trigger

[BrianVallelunga]

I'd like to start a conversation around supporting batches of messages from an Azure Service Bus. A similar request was made for Storage Queues in Azure/azure-webjobs-sdk#625

Ideally, I'd be able to specify something like:

public void Handle([ServiceBusBatchTrigger("myqueue", 25)] BrokeredMessage[] messages)
{
  // Process the batch of messages  
}

There are a lot of scenarios where batching message processing is far more efficient than working with an individual message. In my specific case, I'm doing database inserts and those could be done much more efficiently in a batch.

I'm going to look into a similar project that supports Storage Queues: https://github.com/ealsur/WebJobs.Extensions.GroupQueueTrigger

Is this something others would be interested in?

I think this would be extremely useful. I ran a simple test to use the ServiceBusTrigger in a WebJob S2 instance and the performance I got was about 22 messages a second. The current model is just not sufficient for higher throughput.

The sample I am using is here https://github.com/tcsatheesh/samples/tree/master/ServiceBusTrigger

If you change the PrefetchCount and MaxConcurrentCalls to say 100 and 100. I still only see a throughput of 21msg/sec.

Related to Azure/azure-webjobs-sdk#570, but keeping this one open due to the completness of the request.

Are there any work in progress with this issue?

[mishakogan]

I have the same exact issue but for azure storage queues. I need to subscribe to a "batch" of queue messages instead of just one using Azure Functions.
What is the status of this issue? ref: ealsur/WebJobs.Extensions.GroupQueueTrigger#3

Any update on this? Performance of ServiceBusTrigger is just unacceptable (like 5 msg/sec in my case and 10-15% cpu load max).

Our organization would really love to leverage this functionality when it becomes available

This would be great for us also, we use javascript for our funcs so perhaps another config parameter in the binding configuration to specify batch size and max wait time for that batch size

We also have customers asking for this one

ServiceBus batch trigger would be a great option for multiple scenarios.

Can people please thumbs up on the issue rather than +1? +1 causes an email, which I don't really want in this scenario (and now I'm causing an email with this! 😃)

@christopheranderson any updates on this?! Thanks.
